3Required properties:
4 - compatible: Must contain one of the following:
5 - "renesas,usbhs-r8a7790"
6 - "renesas,usbhs-r8a7791"
7 - reg: Base address and length of the register for the USBHS
8 - interrupts: Interrupt specifier for the USBHS
9 - clocks: A list of phandle + clock specifier pairs
10
11Optional properties:
12 - renesas,buswait: Integer to use BUSWAIT register
13 - renesas,enable-gpio: A gpio specifier to check GPIO determining if USB
14 function should be enabled
15 - phys: phandle + phy specifier pair
16 - phy-names: must be "usb"
17 - dmas: Must contain a list of references to DMA specifiers.
18 - dma-names : named "ch%d", where %d is the channel number ranging from zero
19 to the number of channels (DnFIFOs) minus one.
